I have a b&m fuel pressure gauge and it dips when i rev my motor. First, I thought it was my fuel pump. So, I changed the fuel pump out to a walbro and then a GSR. But, it still did the same thing. Then I changed out the fuel filter, it still did the same thing. Lastly, I changed out the fuel pressure regulator and it still did the same thing. You think the fuel gauge is broken? If not, is there anything else that could be going wrong? the pressure is at 42 right now and goes down even though I am reving.

HELP!!!!!!!

how old is the gauge? B&M gauges have a tendancy of going out. see if you can swap it out. maybe borrow a good working gauge from a friend.

Does the car run fine when your moving.. If everything runs good I would guess that its the fuel gauge..

I was going to mention for you to change your fuel filter but I see you already did it..

Re: (93turbo16)
I tried numerous things to fix it...I changed out the fuel pump back to my gsr fuel pump, i changed the washers on the fuel line to the fuel rail...and got a new gas cap...and now it works. Before, when i reved it went down. Now, when i reve it goes up then down. So, its cool.

anyone want to buy an R tranny with a kaaz?

I was gonna suggest fuel pump, but you got it fixed. Good stuff. I had a problem with the nut that held, the fuel line to the rail once. Guys couldn't get the motor running, so it ended up in me and my brothers hands to fix. It was the damn nut, without the orfices, so it didn't let the fuel through. That pissed me off.
